Fats are needed in every cell of our bodies and are vital for regulating blood pressure, strengthening our immune system, and keeping our brains healthy. The human body can produce all the fatty acids it needs except for two - linoleic acid (an omega-6 fatty acid) and alpha-linolenic acid (an omega-3 fatty acid). These are essential fatty acids, and you must get them through your diet.
Omega-6 fatty acids have a pro-inflammatory role, while omega-3 fatty acids have an anti-inflammatory role. Although inflammation helps the immune system fight infection, chronic inflammation in the body can lead to diseases, including heart disease and autoimmune diseases.
